The traffic is driving on the right side of the road, which is standard for North America. The concrete road surface and the style of the guardrails and bridges strongly suggest a major US city highway. The vegetation looks like deciduous trees typical of the mid-Atlantic or Midwestern United States. The overall infrastructure and vehicle types point towards a large metropolitan area. I suspect this is in the United States, likely Chicago, Illinois. I am 40% sure.

The concrete highway with the specific style of overpass and retaining walls is very characteristic of the Chicago expressway system. The lush, dense green trees along the embankment are typical of the Midwest during the summer months. The vehicle density and the layout of the lanes reinforce the impression of a major urban artery. I am becoming more confident that this is indeed Chicago, Illinois. I am 70% sure.
